Cadillac's "no rear drive, no luxury" can definitely rank first.

So do you know the difference between front drive and rear drive?

What is the mainstream driving mode of cars?

Let the professor show you around.

Before the invention of the automobile,

The main tool for humans to ride is a carriage.

After that, the train was invented.

Then the car appeared.

▲ The carriage belongs to the predecessor.

If the analogy is a carriage,

The carriage is pulled by the horse in front to generate electricity.

So of course, the carriage is the driver in front.

▲ Does the train run fast? It's all about the headband.

The power of the train comes from the locomotive.

There is a good saying,

The train runs fast on the headstock.

So the train is naturally the front driver.

1886 After the invention of the automobile,

Mercedes-Benz I was patented in Carl Benz.

▲ Mercedes-Benz 1? The engine is under the seat.

You can see its engine under the seat.

So this car belongs to the form of central rear drive.

But this is a tricycle.

Almost contemporary,

The car invented by Durham is a middle-mounted rear drive.

It's a four-wheeled vehicle.

▲ Early four-wheeled cars

In other words,

The form of modern cars,

Closer to the car invented by Durham.

At the same time, because there is no need to pull the horse in front of the car,

So why not put the engine in front?

With the increasing demand for horsepower,

The number of cylinders in cars began to increase.

From single cylinder to double cylinder,

Add it to the four cylinders and six cylinders, and it becomes twelve cylinders.

The more cylinders, the larger the engine block.

Therefore, in order to install a large enough engine under a car with a certain width,

V-shaped layout has become the mainstream with its more reasonable layout.

This is also the origin of V 12 and V8 engines that many car fans talk about.

The advantages of front and rear drive are obvious.

The vehicle weight ratio of rear-wheel drive vehicles is more reasonable,

This also brings better handling.

▲ The picture shows a typical rear-drive performance car of BMW 3.

So now the mainstream motion model,

Will use the rear drive mode more.

However, the front and rear drives are not without drawbacks.

For example, because the engine is in front,

Therefore, it is necessary to pass through the transmission shaft of the front and rear car bodies.

Transmit power to that rear wheel,

First of all, it will erode the space inside the car.

Causing the rear platform to protrude;

Secondly, it will also lead to the reduction of transmission efficiency.

Therefore, with the same strength,

In fact, rear-wheel drive is more fuel-efficient;

Finally, the structure of rear wheel drive,

It is also destined to cost more.

The price is also more expensive.

Because of the characteristics of front and rear drive,

So now, in addition to some traditional luxury models,

Racing cars that pursue extreme control will also adopt rear-drive mode.

The other thing I want to tell you is,

Wuling Hong Guang, the God Car, also adopts the rear-drive mode.

Then do you know why it is called the magic car?

In fact, the precursor model is not a recent thing.

Shortly after the invention of the car, there were predecessor models.

But because more attention is paid to handling and performance,

Front-wheel drive has not yet become the mainstream.

Due to the energy crisis after World War II,

This is because the previous model,

Put the engine and drive in front,

Fewer parts and simpler structure.

In addition, the front wheel layout has the advantages of good fuel economy,

Because there is no long transmission shaft,

Won't lose so much power.

Another advantage is that,

The space utilization rate of the front drive car is higher.

▲ The predecessor stands for Type-R.

The disadvantages of precursors are also determined by their structures.

Because most of the power components are in the front of the car,

Therefore, the front of the car is heavy and the rear is light, resulting in understeer.

In addition, it is easy to push the head. In terms of handling,

And rear-wheel drive are not an order of magnitude.

Front-wheel drive just caters to the current situation of energy crisis all over the world.

Nowadays, with the increasingly stringent emissions in various countries,

Small displacement has become the mainstream of the market,

It also makes the predecessor a mainstream way.

In addition to front-wheel drive and rear-wheel drive,

With the development of science and technology, four-wheel drive came into being.

▲ BMW XDrive four-wheel drive structure

Just as literally,

The power of a four-wheel drive vehicle is driven by four wheels.

Therefore, it has good operability and certain ability to get rid of difficulties.

This is why most off-road vehicles adopt four-wheel drive mode.

But four-wheel drive can't play drift.

▲ Four-wheel drive brings better off-road and trouble-free ability.

The power components of four-wheel drive are becoming more and more complicated.

Therefore, the price is higher in terms of cost and maintenance,

At the same time, the fuel consumption is higher than that of rear drive.

Therefore, some models will launch four-wheel drive models as high-end models.

While raising the price,

And added a stunt to sell cars.

In electricity and age of steam,

Since the pure electric vehicle does not have the engine of the traditional internal combustion engine,

Therefore, the driving modes are more diversified.

In addition, the size of the motor is smaller,

Therefore, the interior layout is more flexible,

Although electric motors are like fuel engines,

There are differences among front drive, rear drive and four-wheel drive.

But because it is driven by a motor,

The motor may be arranged closer to the hub,

Thereby reducing kinetic energy loss.

The development of automobile has always been a dynamic process.

Driving style is becoming more and more flexible and advanced.

Therefore, when the driving mode of the vehicle type is selected,

Nor should we blindly pursue the advanced.

If you want a large space, you may wish to choose a front-wheel drive model;

To experience unparalleled manipulation,

Rear drive is undoubtedly the best choice;

If you are passionate about cross-country,

Four-wheel drive will definitely satisfy you;

Besides, if you want to try early,

Electric car is your better choice.
